Frequently Asked Questions
Why use a treemap instead of a pie chart for web traffic sources?+
Analytics platforms typically report 7 to 12 traffic channels; a treemap displays both major channels and smaller emerging referrers with clean internal labels.
What is a healthy organic + direct share for a content or utility site?+
High-authority SaaS and utility tools typically generate 60% to 80% of total sessions from combined Organic Search and Direct repeat navigation.
Can I plot attributed revenue ($) per channel instead of sessions?+
Yes, enter attributed conversions or revenue ($) per channel in Series A to see which channels drive actual dollar value.
